Two clocks on one weekend
Kumoricon runs 13 to 15 November 2026 at the Oregon Convention Center. The organiser sells two products on separate clocks. The badge ladder ends on 7 November. The room block closed on 21 October.
The badge ladder
The organiser prices a full weekend badge for ages 13 and over at $65 until 7 February, $75 until 9 May, $85 until 8 August, $95 until 7 November and $100 at the door. Ages 6 to 12 pay $25, $30, $30, $35 and $35 across the same five columns. Memberships for ages 5 and under are free.
Three of those rungs have closed. The live price is $95 until 7 November. The door price adds $5, which is 5.26 percent of the closing rung.
Single days sell at the door for $55 on Friday, $60 on Saturday and $55 on Sunday. A child single day is $20. Online single-day sales open at 9pm the night before, and door sales open at 8am.
Two terms govern the badge. Memberships are nonrefundable. Memberships cannot be sold.
The block that closed on 21 October
Four properties publish a rate for the weekend. The table heads its column "Rates starting from". Hyatt Regency Portland at the Oregon Convention Center, 375 NE Holladay St, quotes $235 a night. Courtyard Portland Downtown/Convention Center at 435 NE Wasco St quotes $214. Hotel Eastlund at 1021 NE Grand Ave quotes $199. DoubleTree by Hilton Hotel Portland at 1000 NE Multnomah St quotes $185.
The rates exclude taxes and fees. The organiser puts Portland's occupancy tax at 16.5 percent and marks the figure subject to change.
Reservations closed on 21 October 2026. The page still prints "Booking is open now" and tells readers not to wait because the blocks often sell out before that date.
What three nights and a badge cost
Three nights at the DoubleTree run $555 before tax and $646.58 after it. The $95 badge equals 14.7 percent of that taxed stay. Three nights at the Hyatt run $705 before tax and $821.33 after it, which puts the same badge at 11.6 percent.
The badge money moves in the week before the convention. The room money moves later. A card holds a room and is charged on arrival. A change or cancellation carries no fee at 72 hours or more before check-in.
Where the risk sits
The organiser holds the badge cash from the moment of purchase. It states that it may receive a small portion of the reservation fee on a block booking. It also states that rooms booked direct or through another site may not be counted toward the block.
The property holds the room revenue. It publishes a floor rate, keeps a free exit open to 72 hours, and depends on the guest arriving. The block deadline passed five days before this read, so the pickup number is settled.
The call
The organiser captures the value of this convention. Three terms carry that conclusion.
Timing is the first. The badge price is set and taken months before the doors open, and the purchase carries no refund.
The second is the block design. The organiser negotiates the four rates, publishes them on its own page, and tells members that a block booking supports the convention.
The third is the fee share. The organiser can earn on the badge and again on the reservation.
The property earns on three nights at a published floor rate with the cancellation risk held to 72 hours. The 2025 edition closed at 11,714 paid members and 660 staff. That count sizes the demand a 13 November block serves.
What a revenue manager does with it
Treat 21 October as a pickup date. The blocks had closed by 22 October, so open-market demand for the three nights is readable from that point.
Watch the 72-hour window. A released 13 November room lands after the block closed, and the property resells it at its own rate.
Read the organiser's booking message as a channel instruction. It points members at the block, and the block is where the organiser's rate floor sits.
